The nice thing about a stiff beam is that it won’t sag much. The not-so-nice thing is that it won’t `give’. In new construction, wood framing more or less starts from the ground up; wood members are placed on top …

Deflections of Wood Beams
When we examine deflections of wood members (beams, joists, rafters, girders, etc.) we generally look at two kinds, actually three … the deflection due to the `live load’, e.g., people walking on a floor, wind on a wall, and so …
C & C
(c) Jeff R. Filler, Pell City, April 2023 `Components and Cladding’ … or C & C or `see and see’. In earlier posts we looked at the Main Wind Force Resisting System (MWFRS) wind forces on a couple buildings, specifically, …
`Corners’
(c) Jeff R. Filler, Pell City, April 2023 In earlier posts we looked at the `main’, or `overall’, wind forces on a rather low, wide `shop’ (here and here), and on a relatively narrower and taller `house’ (here). Specifically, we …
Wind Load on Shop Eaves – ASCE 7-22 – Envelope Procedure – MWFRS
Now let’s look at the wind loading on the shop eaves. We ignored them previously, as we were getting `big picture’ wind loads on the building as a whole … or at least an 8-ft `swath’ of building, as a …

Wind Forces on a House (Compared to a `Shop’) – ASCE 7-22 – MWFRS – Envelope Procedure
(c) Jeff R. Filler, Pell City, April 2023 In previous examples (here and here) we looked at the horizontal and vertical wind forces on a `shop’. The shop is/was a `pretend’ structure in a real location, Latah County, Idaho. It …

Wind Load on a Shop – Envelope Procedure – Part 3 – Vertical (Uplift) Forces
In an earlier example (here) we looked at the total horizontal force acting on an 8-foot `swath’ of a shop building, the idea being that the shop is supported by trusses on posts at 8 foot (ft) on center (o.c.), …

Cantilever Post Deflection (Post and Bracket)
Let’s look at a post, say in a shop, or a barn, acting as a vertical cantilever. This means that the base of the post is held rigid (not allowed to rotate), while a lateral (horizontal, or sideways) load is …
Differential Displacements and the SST SDPW Deflector Screw
Differential Deflections … and the Simpson Strong-Tie Strong-Drive® SDPW Deflector Screw (c) Jeff R. Filler, May 2022, Pell City, AL I haven’t tried one out yet … the Simpson Strong-Tie Strong-Drive® SDPW Deflector Screw … but the idea is fascinating …

Case(s) in Point
In the example (here) I discussed a person standing on a wood plank, and `examining’ the deflection. Talk is cheap. I grabbed three pieces of lumber (that I milled) in my shop: one piece a 1 x 5 Southern Pine …
